I have calculated three statistic values for observed vs simulated data. I want to add these defined output values (i.e. the cor_Manual_Urbano, bias_da_Manoel_Urbano, NASH_Manoel_Urbano) to the scatter plot of oberserved vs simulated. There is the additional problem that the output result for cor_Manual_Urbano produces a matrix but I only want to display the correlation value between the two variables. I also want to add a line of best fit to the scatter plot. Here is my code so far:

%pearsons%
cor_Manoel_Urbano = corrcoef(combined_data.Observed_Manoel_Urbano,combined_data.Simulated_Manoel_Urbano, 'Rows', 'pairwise')
%bias%
just_Manoel_Urbano = combined_data(:, [11,22]);
cleaned_Manoel_Urbano = rmmissing(just_Manoel_Urbano);
observedmean_Manoel_Urbano = mean(cleaned_Manoel_Urbano.Observed_Manoel_Urbano);
simulatedmean_Manoel_Urbano = mean(cleaned_Manoel_Urbano.Simulated_Manoel_Urbano);
bias_da_Manoel_Urbano = 100*((observedmean_Manoel_Urbano-simulatedmean_Manoel_Urbano)/observedmean_Manoel_Urbano)
%NASH%
DATA_NASH_Manoel_Urbano = [combined_data.Observed_Manoel_Urbano,combined_data.Simulated_Manoel_Urbano];
DATA_NASH_Manoel_Urbano(any(isnan(DATA_NASH_Manoel_Urbano), 2), :) = [];
NASH_Manoel_Urbano = NSE(DATA_NASH_Manoel_Urbano(:,1), DATA_NASH_Manoel_Urbano(:,2))
%scatter%
figure22 = figure('Name','Scatter Manoel Urbano','Color',[1 1 1]);
scatter(cleaned_Manoel_Urbano.Observed_Manoel_Urbano, cleaned_Manoel_Urbano.Simulated_Manoel_Urbano, 'k')
xlabel('Observed','FontName','Calibri','FontSize',12)
ylabel('Simulated', 'FontName','Calibri','FontSize',12)
title('Manoel Urbano','FontName','Calibri','FontSize',14);
set(gcf,'Position',[100 100 400 400])
